Question

decide whether each expression is less than 100 or greater than 100.
less than 100
greater than 100
18 ÷ 0.1
9 ÷ 0.1

Explanation:

Step1: Calculate $18\div0.1$

$18\div0.1 = 18\div\frac{1}{10}=18\times10=180$

Step2: Calculate $9\div0.1$

$9\div0.1 = 9\div\frac{1}{10}=9\times10=90$

Step3: Compare to 100

$180>100$, $90<100$

Answer:

• Less than 100: $9\div0.1$
• Greater than 100: $18\div0.1$
